**774The petitioner, Stephen D. Nelson, filed this habeas action alleging that he had received ineffective assistance of counsel at two criminal jury trials, both of which resulted in convictions and lengthy prison sentences.1 The respondent, the Commissioner of Correction, moved to dismiss the action pursuant to Practice Book § 23-29 (5),2 based on the terms of a stipulated judgment, filed by the petitioner and the respondent in connection with a previous habeas action concerning the same two trials, that barred the petitioner from filing any further such actions pertaining to those trials. The habeas court granted that motion, and the petitioner appeals,3 claiming that he did not knowingly and voluntarily enter into the stipulated judgment and, therefore, that the habeas court improperly granted the **775respondent's motion to dismiss. We conclude that the petitioner did not properly raise his challenge to the enforceability of the stipulated judgment in the habeas court and, further, that the stipulated judgment was a legally sufficient ground for dismissal of the present habeas action. We therefore affirm the judgment of the habeas court.
The record reveals the following undisputed facts and procedural history. The petitioner was charged with two counts each of kidnapping in the first degree, robbery in the first degree, and burglary in the first degree, and with one count each of conspiracy to commit robbery in the first degree, assault in the first degree, and larceny in the first degree after he and an accomplice allegedly broke into a *954Wethersfield home and proceeded to assault, rob and kidnap the occupant. Following a jury trial, the petitioner was found guilty of conspiracy to commit robbery in the first degree and not guilty of larceny in the first degree. The jury was unable to reach a verdict on the remaining charges, however, and the trial court, Vitale, J. , declared a mistrial with respect to those charges. The court thereafter rendered judgment of conviction and sentenced the petitioner to a term of imprisonment of eighteen years, and, on appeal, the Appellate Court affirmed the judgment of the trial court. See State v. Nelson , 105 Conn.App. 393, 418, 937 A.2d 1249, cert. denied, 286 Conn. 913, 944 A.2d 983 (2008). The petitioner then filed a timely application under General Statutes § 51-1954 with the sentence review division of the Superior Court,5 **776seeking a reduction of his sentence. The sentence review division, however, denied the petitioner's request and upheld his sentence. See State v. Nelson , Superior Court, judicial district of New Britain, Docket No. CR-05-220383-A, 2008 WL 2746485 (June 24, 2008).
The petitioner subsequently was retried on certain of the charges for which a mistrial had been declared in his first trial, and the jury found him guilty of the kidnapping, assault, and burglary charges.6 The trial court, D'Addabbo, J. , sentenced the petitioner to fifty-five years incarceration, to run concurrently with the eighteen year sentence that had been imposed following the petitioner's first trial. On appeal, the Appellate Court reversed the trial court's judgment in part on double jeopardy grounds, remanding the case to the trial court with direction to merge the petitioner's two kidnapping convictions and to vacate the sentence imposed for the conviction of one of those counts. See State v. Nelson , 118 Conn.App. 831, 853-54, 862, 986 A.2d 311, cert. denied, 295 Conn. 911, 989 A.2d 1074 (2010). The Appellate Court affirmed the judgment in all other respects. Id., at 833-34, 986 A.2d 311. The petitioner failed to apply for sentence review within thirty days, as required by § 51-195.
In addition to his direct appeals from the judgments of conviction that were rendered following his two trials, **777the petitioner filed two separate habeas petitions as a self-represented party, one on August *9556, 2007, and a second petition on April 16, 2008. The two actions were consolidated, and, on April 8, 2011, the petitioner's then newly appointed counsel filed an amended petition alleging ineffective assistance of counsel at both of the underlying criminal trials. Thereafter, the petitioner and the respondent jointly moved for a stipulated judgment, and the habeas court granted the parties' motion. Under that stipulated judgment, the respondent agreed to the reinstatement of the petitioner's right to file an application with the sentence review division for a reduction of the fifty-five year term of imprisonment that the petitioner received following his second trial. For his part, the petitioner agreed to be foreclosed from filing any future civil actions challenging the judgments of conviction arising out of his first and second trials and, further, that the remaining counts of the then pending habeas petition were to be stricken with prejudice.7
Thereafter, consistent with the terms of the stipulated judgment, the petitioner filed an application for sentence review pursuant to § 51-195, seeking a reduction of his fifty-five year term of imprisonment. In his application, the petitioner sought credit for his cooperation as a state's witness in a murder case, cooperation that had occurred following the imposition of the fifty-five year sentence. Again, however, the sentence review **778division declined to modify the petitioner's sentence. See State v. Nelson , Superior Court, judicial district of New Britain, Docket No. CR-05-220383-A (November 2, 2012) (54 Conn. L. Rptr. 904). In reaching its decision, the sentence review division explained that it could not lawfully consider the petitioner's cooperation with the state because that cooperation did not take place until after the petitioner's sentencing, and, therefore, the sentencing court could not have known about it. State v. Nelson , supra, 54 Conn. L. Rptr. at 905 ; see General Statutes § 51-196 (a) ("[t]he review division ... may order such different sentence or sentences to be imposed as could have been imposed at the time of the imposition of the sentence under review" [emphasis added] ).
Several months later, on February 14, 2013, the petitioner brought the present habeas action, once again alleging various deficiencies in the underlying judgments of conviction. Subsequently, on August 26, 2015, the respondent moved to dismiss the action under Practice Book § 23-29 (5), on the ground that it was barred by the plain terms of the stipulated judgment. The petitioner objected to the motion and filed a memorandum of law challenging, for the first time, the validity of the stipulated judgment.
In that memorandum of law, the petitioner explained that, while his previous habeas petitions were pending, he had testified as a state's witness in a murder trial in exchange for the state's promise to support a modification of his sentence from a fifty-five year term of imprisonment to one of thirty years. See General Statutes § 53a-39 (b) (providing that sentencing court may modify sentence for "good cause *956shown" at "[a]ny time during the period of a definite sentence of more than three years, upon agreement of the defendant and the state's attorney to seek review of the sentence"); State v. Dupas , 291 Conn. 778, 781-82, 970 A.2d 102 (2009) (trial court properly considered defendant's postconviction **779testimony against codefendants pursuant to modification agreement by state and defendant under § 53a-39 ). The petitioner further explained that, after his testimony on behalf of the state in that murder case, he had agreed to the stipulated judgment, resolving the consolidated habeas petitions in the belief that he would be able to obtain the agreed on sentence reduction by way of his application to the sentence review division for a sentence modification. According to the petitioner, however, the state, upon learning that he had sought sentence review by the sentence review division, rescinded its promise to support a reduction of his prison sentence from fifty-five years to thirty years.
The petitioner further claimed that he would not have agreed to the stipulated judgment if he had known either (1) that seeking a sentence modification in the sentence review division, rather than a reduction of his sentence in the trial court, would cause the state to rescind its promise to him, or (2) that the sentence review division would be unable to consider his cooperation with the state as a witness in the murder trial. He blamed his ignorance of these facts on the allegedly ineffective assistance that he received from the two attorneys working simultaneously on his case-one representing him in pursuing a sentence reduction under § 53a-39 (b) and the other representing him in connection with the habeas petition that ultimately was resolved by the stipulated judgment.
Notwithstanding these assertions, the habeas court, Oliver, J. , granted the respondent's motion to dismiss the present action, explaining, in response to the petitioner's subsequent motion for articulation, that, "in exchange and for the consideration of the restoration of his right to file an application for sentence review, [the petitioner] agreed that he is foreclosed from future civil litigation challenging the convictions related to [the instant habeas petition]." The court did not address **780the petitioner's argument-raised solely in his memorandum of law in opposition to the respondent's motion to dismiss-that the stipulated judgment was invalid because the waiver of his rights contained therein was not knowing and voluntary due to the failure of counsel to inform him of the apparent consequences of entering into the stipulated judgment, in particular, that the sentence review division would not consider a reduction of his sentence based on his cooperation with the state.
On appeal, the petitioner claims that the habeas court, in ruling on the respondent's motion to dismiss, should have construed his memorandum of law and the facts asserted therein in the light most favorable to the petitioner, just as it would have construed the facts alleged in the habeas petition. The respondent contends that the habeas court properly dismissed the action in accordance with the express terms of the stipulated judgment because the petitioner's challenge to the validity of that judgment, which the petitioner raised for the first and only time in his memorandum of law, should have been raised in the petition itself and, therefore, was not properly before the habeas court on the respondent's motion to dismiss. We agree with the respondent.
It is well established that, when a habeas court considers a motion to dismiss a petition for a writ of habeas corpus, "[t]he evidence offered by the [petitioner] is to be taken as true and interpreted in *957the light most favorable to [the petitioner], and every reasonable inference is to be drawn in [the petitioner's] favor." (Internal quotation marks omitted.) Ham v. Commissioner of Correction , 152 Conn.App. 212, 223-24, 98 A.2d 81, cert. denied, 314 Conn. 932, 102 A.3d 83 (2014) ; see also Orcutt v. Commissioner of Correction , 284 Conn. 724, 739, 937 A.2d 656 A.29 656 (2007). It is equally well settled that "[t]he petition for a writ of habeas corpus is essentially a pleading and, as such, it should conform generally to a complaint in a civil action ... [and it] is fundamental **781in our law that the right of a plaintiff to recover is limited to the allegations of his complaint." (Internal quotation marks omitted.) Thiersaint v. Commissioner of Correction , 316 Conn. 89, 125, 111 A.3d 829 (2015). Thus, "[w]hile the habeas court has considerable discretion to frame a remedy that is commensurate with the scope of the established constitutional violations ... it does not have the discretion to look beyond the pleadings and trial evidence to decide claims not raised.... The purpose of the [petition] is to put the [respondent] on notice of the claims made, to limit the issues to be decided, and to prevent surprise." (Internal quotation marks omitted.) Newland v. Commissioner of Correction , 322 Conn. 664, 678, 142 A.3d 1095 (2016). In the present case, it is undisputed that the petitioner's habeas petition did not allege ineffective assistance predicated on counsel's failure to properly advise the petitioner regarding the waiver of his habeas rights under the stipulated judgment, nor did the petition allege any other defect in the stipulated judgment. As a result, the habeas court properly declined to consider those issues in connection with the respondent's motion to dismiss.
We disagree with the petitioner that the assertions contained in his memorandum of law were on equal footing with the allegations contained in the habeas petition and, therefore, should have been taken as true and viewed in the light most favorable to the petitioner. It is clear that a memorandum of law is not a proper vehicle for supplementing the factual allegations in a complaint; see, e.g., Practice Book § 10-31 (party responding to motion to dismiss shall have thirty days to file "a memorandum of law in opposition and, where appropriate, supporting affidavits as to facts not apparent on the record " [emphasis added] );
**782Connecticut Independent Utility Workers, Local 12924 v. Dept. of Public Utility Control , 312 Conn. 265, 281, 92 A.3d 247 (2014) ("[T]o the extent that the plaintiffs contend that memoranda of law or exhibits submitted to the trial court cured any potential deficiencies in their allegations, they are mistaken.... Memoranda of law are not pleadings."); see also Morgan Distributing Co. v. Unidynamic Corp. , 868 F.2d 992, 995 (8th Cir. 1989) ("it is axiomatic that a complaint may not be amended by the briefs in opposition to a motion to dismiss" [internal quotation marks omitted] ), quoting Car Carriers, Inc. v. Ford Motor Co. , 745 F.2d 1101, 1107 (7th Cir. 1984), cert. denied, 470 U.S. 1054, 105 S.Ct. 1758, 84 L.Ed. 2d 821 (1985) ; In re Colonial Ltd. Partnership Litigation , 854 F.Supp. 64, 79 (D. Conn. 1994) ("the new allegations introduced by [a plaintiff] in [his] [m]emorandum of [l]aw in [o]pposition to [a motion to dismiss] ... are not properly before the court on [such] a motion"); and we do not believe that a different rule should pertain to habeas petitions. See Kendall v. Commissioner of Correction , 162 Conn.App. 23, 45, 130 A.3d 268 (2015) ("[a] habeas corpus action, as a variant of civil actions, is subject to the ordinary rules of civil procedure, unless superseded by the more specific rules pertaining to habeas actions").
*958In reaching our decision, we are mindful that, although the petitioner filed the present habeas petition as a self-represented party on February 14, 2013, he was represented by counsel as of June 14, 2013, more than two years before the respondent, on August 26, 2015, filed the motion to dismiss that is the subject of this appeal. Furthermore, under Practice Book § 23-32,8 the petitioner was entitled to amend his petition "at any time prior to the filing of the return" on September 11, 2015, or for good cause thereafter.9 Accordingly, even after the respondent filed the motion to dismiss, **783the petitioner had two weeks in which to amend his habeas petition as of right to include a claim challenging the enforceability of the stipulated judgment, but he failed to do so.10 Instead, the petitioner raised the issue only in his memorandum of law responding to the motion to dismiss.11 As we have explained, however, the habeas court properly declined to look beyond the allegations in the habeas petition in deciding the motion to dismiss; see Newland v. Commissioner of Correction , supra, 322 Conn. at 678, 142 A.3d 1095 ; and, accordingly, the petitioner cannot prevail on his claim that the habeas court was required to consider the assertions contained in the petitioner's memorandum of law related to the stipulated judgment.12 **784*959The petitioner nonetheless contends that, under Fine v. Commissioner of Correction , 147 Conn.App. 136, 81 A.3d 1209 (2013), the respondent was required to make an affirmative showing that the petitioner knowingly and voluntarily waived his right to future habeas relief under the stipulated judgment and that the respondent failed to make such a showing in the present case. In light of the plain terms of the stipulated judgment, however, we disagree that Fine imposes such a burden in this case.
In Fine , the respondent moved to dismiss a petition for a writ of habeas corpus on the ground that the petitioner, Paul Fine, had withdrawn a prior petition involving identical allegations of ineffective assistance of counsel "with prejudice," thereby waiving his right to pursue the claims contained in the petition in any future habeas action. Id., at 137-38, 141, 81 A.3d 1209. The habeas court granted the motion, but the Appellate Court reversed, concluding that the respondent had failed to make "an affirmative showing that, at the time of the withdrawal, the petitioner was apprised of and understood the right being waived and the consequences of his waiver." Id., at 147-48, 81 A.3d 1209. The court noted that the respondent had failed to introduce a transcript of the relevant proceedings, that the petitioner's prior counsel was not called as a witness, that the parties offered conflicting testimony regarding the proceedings, and, crucially, that even the withdrawal form did not indicate that a withdrawal with prejudice had occurred. Id., at 146-47, 81 A.3d 1209. Thus, the court in Fine was required to determine, on the basis of a murky record and in the face of contradictory testimony, **785whether there was sufficient evidence of record to support even a prima facie showing that the petitioner had knowingly and voluntarily waived his right to future habeas relief in a prior proceeding. By contrast, the nature of the decision of the prior habeas court in the present case was clearly set forth in the stipulated judgment and is not disputed: the parties agree that the prior judgment by its terms barred further habeas actions relating to the petitioner's two trials. See Doe v. Roe , 246 Conn. 652, 664-65 n.22, 717 A.2d 706 (1998) (stipulated judgment is "a contract of the parties acknowledged in open court and ordered to be recorded by a court of competent jurisdiction ... [and] is binding to the same degree as a judgment obtained through litigation" [citation omitted; internal quotation marks omitted] ). Consequently, Fine , a case involving a purported agreement of highly uncertain terms, is readily distinguishable from the present case.13
Finally, we reject the petitioner's argument that habeas rights simply are not subject to waiver at all. This court has concluded that both constitutional rights; see Mozell v. Commissioner of Correction , 291 Conn. 62, 71, 967 A.2d 41 (2009) ; and appellate rights; see Molinas v. Commissioner of Correction , 231 Conn. 514, 523-24, 652 A.2d 481 (1994) ; may be waived, if the waiver represents the intentional relinquishment of a known right. Furthermore, the Appellate Court has held that a habeas court may accept the withdrawal of a habeas *960petition "with prejudice," allowing the petitioner to waive any future habeas rights, as long as the **786withdrawal is knowing, voluntary, and intelligent. See Mozell v. Commissioner of Correction , 147 Conn.App. 748, 758 and n.10, 83 A.3d 1174, cert. denied, 311 Conn. 928, 86 A.3d 1057 (2014) ; see also Fine v. Commissioner of Correction , supra, 147 Conn.App. at 147 n.2, 81 A.3d 1209 ("we see no need to foreclose the possibility that, prior to trial, a petitioner may withdraw a habeas petition with prejudice, perhaps after having reached a mutually satisfactory agreement with the respondent"). Indeed, in other jurisdictions, such collateral attack waivers are enforceable as a general rule. See, e.g., United States v. Lemaster , 403 F.3d 216, 220 (4th Cir. 2005) ("a criminal defendant may waive his right to attack his conviction and sentence collaterally, so long as the waiver is knowing and voluntary"); Frederick v. Warden, 308 F.3d 192, 195 (2d Cir. 2002) ("[t]here is no general bar to a waiver of collateral attack rights in a plea agreement"), cert. denied sub nom. Frederick v. Romine , 537 U.S. 1146, 123 S.Ct. 946, 154 L.Ed. 2d 847 (2003) ; Jones v. United States , 167 F.3d 1142, 1145 (7th Cir. 1999) (waivers of collateral attack rights are generally enforceable, except with respect to claims relating directly to negotiation of waiver in question). The undisputed importance of the writ of habeas corpus notwithstanding; see Lozada v. Warden, 223 Conn. 834, 840, 613 A.2d 818 (1992) ("the principal purpose of the writ of habeas corpus is to serve as a bulwark against convictions that violate fundamental fairness" [internal quotation marks omitted] ); the petitioner has not persuaded us that a different rule should apply to such writs in this state.
In sum, in order to forestall dismissal of his habeas petition on the basis of the prior stipulated judgment, the petitioner, at any time before the filing of the return on September 11, 2015, or by permission of the court thereafter; see Practice Book § 23-32 ; could have amended his habeas petition to allege ineffective assistance of counsel predicated on counsel's failure to properly **787advise him regarding his waiver of habeas rights under the stipulated judgment. Indeed, as the respondent essentially conceded at oral argument, had the petitioner done so, the petition would not have been subject to dismissal because the amended petition would have raised a genuine issue of fact as to whether the stipulated judgment constituted a legally sufficient ground for dismissal under Practice Book § 23-29 (5). Because the petitioner failed to make this amendment, however, the habeas court properly granted the respondent's motion to dismiss the petition. As a consequence, the petitioner will have to file a new petition properly alleging ineffective assistance of habeas counsel in connection with the prior proceedings.14
The judgment is affirmed.
In this opinion the other justices concurred.
